     [ https://issues.apache.org/jira/browse/MAPREDUCE-918?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Aaron Kimball updated MAPREDUCE-918:
------------------------------------

    Attachment: MAPREDUCE-918.patch

Reconfigure hsqldb to use {{jdbc:hsqldb:mem}} protocol which is an in-process, in-memory configuration. Simultaneous tests no longer collide.

> Sqoop launches a standalone hsqldb server for unit tests, but it currently writes its database to disk and uses a connect string of {{//localhost}}. If multiple test instances are running concurrently, one test server may serve to the other instance of the unit tests, causing race conditions.
